The IN518 is typically housed in a small-form-factor package, such as an SOP-8 or MSOP-8. It functions primarily as a DC-DC step-up (boost) converter designed to provide the high voltage necessary to drive LED backlights from a low-voltage input source.

• Pin 1 → Ground
• Pin 17 → +5V (with 0.1µF to GND)
• Pin 2 → 25 MHz oscillator output
• Pins 3–10 → 8-bit GPIO from microcontroller (e.g., PORTB of ATmega)
• Pin 11 → Microcontroller PWM for horizontal sync
• Pin 12 → Microcontroller PWM for vertical sync
• Pin 13 → VCC (DE tied high for continuous data)
• Pin 14 → Source driver clock input (e.g., HX8224)
• Pin 15 → Source driver latch
• Pin 16 → Common electrode driver (inversion at 70Hz)
